Shimmering Blue Fish School

Preview of your prompt

Goal: Create a highly detailed vertical marine illustration of a crowded school of fish, like a shimmering watercolor-and-ink poster on a clean white background. Canvas: Portrait orientation, 2:3 ratio, edge-to-edge composition with no frame. Leave small white gaps between fish, and add a tiny date and artist signature in the bottom-right corner. Subject details: Show exactly 55 fish total: 5 large feature fish and 50 smaller baitfish. The 5 large fish are: 1 huge blue tuna-like fish across the top with a tall dorsal fin and large golden eye, partially cropped at the right edge; 1 long silver-and-blue barracuda-like predator across the middle-left with pointed snout and visible teeth; 1 pink-red snapper-like fish on the right-center with golden eye and rosy fins; 1 large deep-blue tuna-like fish across the lower middle with round black eye and pale belly; 1 long silver-blue barracuda-like predator along the lower section with sharp jaw and teeth. The 50 smaller fish are slim sardine or mackerel shapes, mostly swimming horizontally left-to-right or right-to-left, distributed densely between and around the larger fish, with a few partially cropped at the edges. Visual style: Intricate watercolor illustration mixed with fine pen-and-ink linework, bright reflective scales rendered as hundreds of circular sequin-like dots, metallic sparkle, crisp anatomical fish outlines, transparent fins, detailed eyes, and layered blue shadows. Use a luminous ocean palette dominated by cobalt blue, ultramarine, icy white, silver, and pale cyan, with one contrasting fish in pink, coral red, and warm gold. The overall feeling should be refreshing, summery, humid, and bright, like a decorative AI art print. Text content: In the bottom-right corner, add the small printed date July 11, 2026 and a delicate handwritten signature Oyagi. Keep the text tiny and unobtrusive. Constraints: No humans, no scenery, no water surface, no bubbles, no border, no extra typography. Maintain dense fish layering but keep every fish clearly outlined against white negative space.
